SHumo allakay medoned, ki nafaskashi vazifai muhimi organizm buda va uzvhoi nafaskashi qismati dimogi, kom, gortan, shush mahsub meshavand. Dar rohhoi boloii nafas havo az mikrobho toza gardida, hissachahoi begona garmu sernam meshavand. Dar holati mutaasirshavii pardai luobii dimog va kom bo chang reflekshoi himoyati ba amal meoyad – atsa va sulfazadanho.
Pokshavi va garmshavii havo vaqte ba amal meoyad, ki inson bo vositai bini nafas megirad. Dar sinni kudaki nafaskashi bo vositai dahon metavonad ba qafomonii inkishofi jismoni va aqlonii kudak ovarda rasonad.
Nafaskashi iborat ast az tabdili havo bayni muhiti atrof va hubobchahoi shush. Az hisobi harakati mavzuni nafaskashii qafasi sina afzoish yo kamshavii hajmi shushho – nafas ba darun va nafas ba berun ba amal meoyad.
Dar vaqti nafas kashidan mushakhoi nafasgiri khurd, ikhcham meshavand, ki onho qaburgahoro bolo namuda, diafragmaro poyon mesozad, hajmi qafasi sinaro ziyod mekunad yo meafzoyad. SHushho dar in hol vase megardand va havo guyo dar on furu burda meshavad. Nafaskashi surat megirad (rasmi 10, az chap).
Agar shumo pas az tanaffusi kalon yo muddati tuloni ba mashqhoi jismoni mashgul shudan, ki nafaskashii faolro talab mekunad, ruzi digari pas az mashqkuni dardro dar mushakhoi sina ehsos menamoed. In guyandai on ast, ki mushakhoi nafaskashi sarborii muayyan giriftaand.
Pas az nafaskashi mushakhoi bayniqaburgavi sust gashta, qaburgaho poyon shuda, diafragma ba holati peshtaraash barmegardad. Dar natijai on fishor dar qafasi sina ziyod gardida, shushho fishurda meshavand va havo ba berun tela doda meshavad.
Nafas barovardan in tarz surat meyobad (rasmi 10, az rost). Tavre, ki mebinem on be ishtiroki faoli mushakho ba anjom merasad.
Tedodi nafaskashi dar yak daqiqa rejai nafasiro tashkil medihad. YAne dar odamone, ki ba mashqhoi jismoni mashgul nestand, rejai nafasgiri az 10-12 nafasgiri dar yak daqiqa iborat ast. Vale dar odamoni mashqkunanda, ki ba mashqhoi jismoni va varzish payvasta mashguland, on du marotiba kam 5-6 nafasgiri dar yak daqiqa ast.
Mashqhoi jismoni imkoniyathoi funksionalii sistemahoi nafaskashiro baquvvat menamoyad; vase menmoyad; hajmi sofkunii shush, quvvai mushakhoi nafasi ziyod meshavad va gayra.
Tagyirot dar sharoiti faoliyati inson ba protsesshoi turshshavi dar organizm tasir merasonad. YAne hangomi mashguliyatho bo mashqhoi jismoni yo korhoi jismonii vaznin organizm ba oksigeni beshtar ehtiyoj dorad.
Afzoishi surati harakathoi nafasi yo kamshavii on ba tavri avtomati ba amal meoyad. In aksulamali nafas ba tagyiryobii rejai korii sistemai nafaskashi ba qonegardonii talaboti zarurii organizm ba oksigen ravon gardidaast.
Baroi inkishofi sathi faoliyatnokii inson sharoit roli muhim mebozad, ki dar on mashguliyathoi mashqhoi jismoni meguzarand. YAke az chunin sharoitho guzaronidani mashguliyatho dar kuhho meboshad.
Fishori pasti havo, kam budani oksigen dar havo ba kamshavii oksigen dar tarkibi khuni mashqkunandagon ovarda merasonad.
Mahz baroi hamin mashguliyat dar sharoiti kuhsor ba mutobiqshavii bisyor uzvho ba kor yo faoliyat dar holati kam budani oksigen dar khun musoidat menamoyad, dar natija imkoniyathoi funksionali
va faoliyatnokii organizmi inson baland megardad. Asosan dar in jarayon – faoliyati sarfakoronai uzvho va sistemai organizm, azkhudkunii behtaru beshtari oksigen, mutobiqgardonii sistemai mushaki faoliyatkuni dar holati kambudi oksigen ba amal meoyad.
Bo mururi solho hajm va sathi boloi nafaskashii shushho meafzoyand. Vositai muhimtarini mashguliyatguzaroni va takmili sistemai nafaskashi faoliyatnokii mushaki meboshad.
Mashguliyathoi payvastai mashqhoi jismoni va varzish sarhadhoi imkoniyathoi funksionalii sistemahoi nafaskashiro meafzoyad.
